HEAT CONTROL DEVICE Filed Dec. 20. 1960 from/EY United States Patent O Mce 3,i,26 HEAT C@ TRL DEWQE Manrice iv/ih Widener, e569 Bevonshirc Eris/e, San lose, Caiif. Filed Dec. 20, Noti, Ser. No. 77,@6 7 tCiairns. (Cl. 21M-i3) This invention relates to a heat control device, and in particular to an improved means for quickly bringing a contained substance to a desired temperature, and for maintaining such substance at the desired temperature.
For the purpose of simplicity of explanation, the following description is directed particularly to the use of the heat control device of this invention for warming a baby milk bottle, for which the inventive device is especially applicable. However, it is to be understood that the scope of this invention is not limited to such use only. Also, all references to temperature will define degrees in Fahrenheit hereinafter.
In the prior art, milk which is contained in bottles for feeding infants is usually stored in a refrigerating environment, and maintained at a Very low temperature, such as 35-40 degrees. When it is necessary to use the refrigerated milk to feed an infant, the milk must be heated rapidly to a temperature which will not bring discomfort to the infant. However, with presently known systems and devices for rapid heating of bottled milk, it is diicult to arrive at a proper temperature in a short time. Often the milk is overheated so that it must be cooled, or the milk is heated incrementally several times and needs to be checked often before it is brought to the desired temperature. Furthermore, many of these devices comprise several parts, require electric or other power supplies, are not waterproof, and are subject to breakage. Such devices and systems thus are lacking in efficiency, may be time consuming and costly, and have proven to be nuisances.
It is known that refrigerated milk is generally maintained at about 35-40 degrees. It is also known that the hot water which may be obtained from the conventional household water supply attains a temperature of approximately 140 degrees. It would be very desirable to utilize such easily accessible heat energy for heating a baby milk bottle if the heat transfer process can be rapid and controlled.
An object of this invention is to provide a heat control device which affords a quick heating of a contained body to a desired temperature, and which maintains said body at such temperature for a substantially long time.
Another object of the invention is to provide a heat control device for quick heating of a baby milk bottle which does not require electrical heating or other power supplies.
Another object'is to provide a non-metallic, shock resistant, and water-proof container which affords rapid heating of a bottle of baby milk to a desired temperature by simple and economical means.
According to this invention, a heat control device which affords quick heating of a contained body, and maintains such body at a desired terminal temperature comprises a container member and a cooperating cap member, both formed from one and the same material. The configuration and dimensions of the container member are predetermined so that the volume of a heat energy providing substance which is added to the container member during the heating process bears a substantially fixed relationship to the volume of the body to be heated. The cap member and the container member are formed from a highly thermally insulating material having a low thermal coefficient (K factor) and a low specic heat, and when conjoined provide a substantially air sealed enclosure thermally insulated from ambient temperature CII Patented Nov. 3, i964 conditions. By such means, rapid transfer of heat energy between the body and the heat energy providing substance is afforded for heating the body to a predetermined terminal ternperature. Furthermore, the body is thereafter maintained at such temperature for a substantially long time.
in a particular embodiment of the invention, the cap member and the container member consist of a highly thermally insulating material having a low specific heat, such as an expanded polystyrene. The substance to be heated is a bottle of baby milk at a temperature of about 35-46 degrees, whereas the heat energy providing body is readily available household supply hot water at approximately degrees. In accordance with this invention, the baby milk may be heated to a comfort temperature of about 96-98 degrees within approximately six minutes, and remains at such temperature for an extensive time.
The invention will be described in greater detail with reference to the sole figure of the drawing in which:
FEGURE l is a perspective view, in elevation, of a heat control device (with a portion broken away), in accordance with the invention.
in FIGURE 1, a heat control device comprises an enclosure in having a container member l2 and a cap member i4. The member l2 may be cylindrical having a closed end or base llo. The open end has an annular stepped portion 18 for accommodating the cap member M, which has a complementary cooperating peripheral stepped portion 29 that seats closely on the stepped portion i8. When the members l2 and 14 are conjomed, a substantially airtight enclosure lil is formed.
The container member 12 and the cap member 14 are made from an expanded polystyrene, such as the commercially available Dylite, a trademarked product of the Koppers Company, Inc. The polystyrene has a very low thermal coefficient and a low specific heat. Therefore, there is substantially no interchange of heat energy between the internal environment of the enclosure lil and the external surroundings when the members i2 and id are engaged.
To practice the invention, hot water Z2 from a household faucet is permitted to run until it has attained its maximum temperature, which is generally 140 degrees. With a bottle 24 containing a quantity of milk 2e set within the container member 12, the hot water 22 is directed into the member 12 until the water 22 reaches a level substantially at the same height as the level of the milk 2o. The cap member i4 is immediately seated on the container member l2 to provide a closely sealed enclosure lb which conforms closely to the configuration of the bottle 24 and a nipple 2% fastened to the bottle by a threaded annulus Sti in a well-known manner.
Since the material forming the enclosure 1d has a very low lspecific heat, a very loW thermal coefficient, and has a low permeability for water and water vapor, the heat interchange takes place practically between the bottle 24, the nipple 28, the milk 26 and the water 22 only. Furthermore, as the enclosure it) conforms closely to the bottle 24;, there is a minimum amount of air within the enclosure to affect the heat transfer process. Therefore, the interchange of heat energy between the milk 26 and the water 23 is rapid and controlled.
The enclosure l@ also has a raised ribbed portion 32 fabricated on the internal surface of the container base li. When the vessel or bottle 24 is set on the ribbed portion 32, the bottom of the bottle 24 is spaced from the major surface of the container base 16. Such spacing provides more surface area of the bottle 24 for heat interchange. In addition, heat convection currents caused by the contact between the relatively bld bottle 24 and milk 26 and the` hot water 22 traverse longer paths de. fined along the exterior of the cylindrical wall and under i the base le of the bottle 24. Thus the heat transfer process is accelerated.
After the milk 2d and the water 22 have reached a terminal temperature at which there is thermal equilibrium, which would be the desired comfort temperautre of approximately 98 degrees, the temperature of the milk 26 remains substantially constant for many hours. Therefore there is no need for checking of the milk temperature, or reheating or recooling.
If it is assumed that the specic heat and the density of water are substantially the same as the specific heat and the density of milk, the amount of hot water at approximately 140 degrees that is needed to heat quickly a bottle of baby milk which is at about 40 degrees to a comfortable feeding temperature such as 9S degrees, may be determined. The heat transfer relationship is known to be as follows:
where V1 is the volume of hot water 22 in ounces; V2 is the volume of the bottle 24, milk 2d, nipple 255 and fastener 3@ in ounces; and F. is the temperature in degrees Fahrenheit.
From Equation l, it is seen that the volume of hot Water V1 should be approximately 1.4 times V2. lt has been determined that commercially available baby milk bottles, when assembled with the nippie and annular fastener, displace a volume of approximately 3 ounces. Therefore the additional volume of hot water required for the heating of the milk bottle only is about 4.2 ounces. lf 8 ounces of milk is to be heated, then about 11.2 ounces of hot water at 140 degrees is necessary to heat the milk to` 98 degrees.
lt is also readily determined that for a given height h,
where r1 is the inner radius of the container member 12, and r2 is the outer radius of the bottle 24. Since we know r2, the radius of the baby bottle 2d, and as we know the volume V2 of milk to be heated, for example 8 ounces, then we may determine V1 (approximately 15.4 ounces for 8 ounces of milk) and solve for the radius r1 of the container member 12.
An a specific embodiment of the invention, the container member l?. was fabricated from Dylite, an expanded polystyrene foam, having a thickness of about one-half inch and a density of 2.5 lbs. per cubic foot. The inner diameter of the container member l2 was about 31/2 inches, the height of the cylindrical container member was approximately inches, with the inner shoulder of the stepped portion 13 being recessed about inch.
The cap member 14 when seated on the container member 12 has a height of approximately three inches above the member 12 so as to accommodate the nipple 23 in close spaced relation.
In another form, indicia 34 may be marked on theinner Wall of the container member 112, such indicia 34 corresponding to the volume of milk to be heated. Therefore, if it is desired to heat 8 ounces of milk to 98 degrees, the container member 12 is first filled with hot water at 140 degrees up to the level designated by the numeral before the bottle 24 is placed in the mem- 12. When the bottle 24 is set into the member l2, the level of the water 28 rises to the proper height, which is just about the height of the milk 26. The position or level of the markings or indicia 34 may be determined by use of the relationships set forth heretofore. In one form, the numerical indica may be disposed on the base lo spaced in circular fashion, between the ribs 32, with corresponding level markers or height indicating protuberances registered vertically in a helical path on the inner cylindrical Wall of the closure member i2.
Such indicia 34 are particularly useful when it is desirable to heat a small quantity of milk, such as two ounces by way of example. Also when plastic bottles which are not transparent are utilized to contain the milk, the use of the level indications which correspond to the necessary volume of hot water is desirable.
lt is understood that the invention is not limited to the conguration illustrated herein. Also the invention is applicable to the use of any material having a very low coefficient of thermal conductivity and a very low specitic heat, for controlling a heat transfer process in a simple, economical and convenient manner.
